The quake struck late Sunday evening while many villagers were finishing dinner or getting ready for bed. People grabbed whatever belongings they could and fled into the cold, spending the night huddled around fires in makeshift camps.

Iran sits on several major fault lines and its history is filled with numerous deadly earthquakes.

A 2003 quake in the southern city of Bam killed at least 26,000 people, while a 2012 quake in East Azerbaijan province killed more than 300.
